Hi.
How about using "Lexus Motor Insurance" Tel 0800 1383200
Open 8-8 Mon - Fri and 8-4 Sat..
Managed on behalf of Lexus GB by Royal & SunAlliance Insurance plc.
Underwritten by Aioi Motor and General Insurance Company of Europe Limited.
Halved my insurance costs when I switched to them from CIS couple of years ago.
Hope this info is useful.
